This doesn't surprise me, because round walls give exactly the same trouble in real life, unless the structure is so very large that the curvature is negligible for the purposes of furniture, wall shelves, etc.
A round house sounds cute until you try to actually furnish one, unless you want nothing at all against the walls, everything clustered in the center.
People do build an ive in dome houses but they remain a fringe thing and it does tend to mean having the only straight walls be interior ones, which makes trouble with cramped rooms unless the dome is a lot larger than dome homes normally are. They get around the cramped feeling by having open concept layouts. But then there's the issue with needing at least some straight walls, and having comparatively few windows or places to put windows.
Theoretically you could warp the entire circumference in windows but if all your plumbing, electrical, and built in storage needs to be on straight interior walls, again it turns into a dark cramped situation.
Things are straight and square and rectangular because we can't have refrigerators, bathtubs, kitchen cabinets, wall paneling and insulation, bookshelves, and beds, all custom fabricated to hug and align with a specific curve radius.
